ChatGPT

ChatGPT is OpenAI's AI assistant — the most widely used AI tool in the world. It can write content, answer questions, analyze documents, generate images (DALL-E), create videos (Sora), write and execute code (Codex), conduct deep research across the web, and handle voice conversations. It powers GPT-5.4 on paid plans.

ChatGPT has five tiers: Free (GPT-5.3, limited messages, ads in US), Go at $8/mo (more messages, still has ads), Plus at $20/mo (full features including Deep Research, Sora, Codex — no ads), Pro at $200/mo (unlimited everything), and Business at $25/user/mo for teams.

Yes. The free tier includes GPT-5.3 with limited messages (roughly 10 per 5 hours), basic image generation, and standard chat. Since February 2026, free tier in the US includes ads. For regular professional use, Plus at $20/mo removes ads and unlocks the full feature set.

For most users, no. Plus at $20/mo includes GPT-5.4 Thinking, Deep Research, Sora video, Codex coding, and Agent Mode. Pro at $200/mo removes all message caps and provides exclusive o1 Pro mode for maximum reasoning depth. Pro only makes sense if you consistently hit Plus limits — which requires very heavy daily use.

Deep Research is an autonomous research agent available on Plus and above. Give it a topic, and it searches the web, reads multiple sources, and produces a comprehensive multi-page report with citations. You get 10 Deep Research runs per month on Plus, unlimited on Pro.

Yes. ChatGPT includes DALL-E for image generation and Sora for video generation on Plus and above. You describe what you want in natural language, and ChatGPT creates it. Image generation is also available on the free tier with limited generations.

On the free and Go plans, OpenAI may use your conversations to improve models. Plus does not guarantee data isolation. For business use, the Business plan ($25/user/mo) and Enterprise plan (custom pricing) guarantee your data is not used for training and include admin controls, SSO, and compliance features.

Go is a $8/mo plan launched in January 2026. It provides more messages than free, handles everyday tasks well, but does not include Deep Research, Sora, Codex, Agent Mode, or GPT-5.4 Thinking. Go also shows ads, like the free tier. It is best for moderate users who need more than free but do not need professional features.

Yes. ChatGPT can write code in any major language. On Plus and above, Codex is an AI coding agent that can execute code in a sandbox, create multi-file projects, and debug complex issues. The free tier can write code but cannot execute it.

ChatGPT has a larger ecosystem (GPTs, plugins, DALL-E, Sora) and is more versatile. Claude produces better writing quality, has a larger context window (200K vs ~128K tokens), and is stronger on safety. Both cost $20/mo for their main paid plan. See our full comparison.

ChatGPT Free costs nothing. Go is $8/month, Plus is $20/month, Pro is $200/month, Team is $25/user/month. Enterprise pricing is custom. The free tier includes GPT-5.3 with limited messages.

Log in to ChatGPT, click your profile icon, select Settings, then Subscription, then Cancel Plan. Your access continues until the end of the billing period. Refunds are not available for partial months.

ChatGPT stands for Chat Generative Pre-trained Transformer. 'Chat' refers to the conversational interface, 'GPT' is the underlying language model architecture developed by OpenAI.

ChatGPT launched on November 30, 2022. It reached 100 million monthly active users within two months, making it the fastest-growing consumer app in history at the time.

For general use, yes. OpenAI applies content filters and safety training. For sensitive work: free and Go tier conversations may be used for model training. Plus, Team, and Enterprise plans offer opt-out. Never share passwords, financial details, or confidential business data with any AI assistant.
